I can confirm that this does not appear to work for me either (with the
perl 5.005_03 in the base system.)

Those paths don't match; double-check that you're running the version of
perl that you think you are.

I wrote a small C program that does essentially what the section of
perl.c that's failing does (call setreuid() twice,) and it works without
problems, so the problem is presumably not setreuid() itself.

So at this point I'm out of ideas... I mean, I dunno, maybe it has to do
with threads? although I don't think the base system perl is built with
threads anyway, so, *shrug* sorry.  That's as far as I can help.
